1. Anthropogenic Radionuclides in the Arctic Ocean: Distribution and Pathways
Abstract : Anthropogenic radionuclide concentrations have been determined in seawater and sediment samples collected in 1991, 1994 and 1996 in the Eurasian Arctic shelf and interior. Global fallout, releases from European reprocessing plants and the Chernobyl accident are identified as the three main sources. READ MORE

2. Eurasian Arctic Tectonics: Geology of Severnaya Zemlya (North Kara Terrane) and Relationships to the Timanide Margin of Baltica
Abstract : The North Kara Terrane (NKT), with Severnaya Zemlya as its main outcrop area, constitutes the Palaeozoic and older rocks of the northern part of the Kara Shelf. Potential field data suggest a continuation into the eastern Barents Shelf. READ MORE

3. Genomic insights into the population history of circumpolar Arctic dogs
Abstract : The Siberian and North American Arctic have both borne witness to numerous migrations of humans and with them their dogs. This PhD thesis is based on whole genome data from 22 Siberian dogs and 72 North American Arctic dogs, in addition to 186 mitochondrial genomes Siberian and North American Arctic dogs. READ MORE

4. Investigating the impacts of Late Pleistocene climate change on Arctic mammals using palaeogenomics
Abstract : The climatic fluctuations of the Late Pleistocene likely had a large impact on the evolutionary history of Arctic species. Palaeogenomics is a useful tool to shed light on how past populations responded to these climatic shifts and the associated ice sheet dynamics and sea level change. READ MORE

5. Compositional clues to sources and sinks of terrestrial organic matter transported to the Eurasian Arctic shelf
Abstract : The amount of organic carbon (OC) present in Siberian Arctic permafrost soils is estimated at twice the amount of carbon currently in the atmosphere. The shelf seas of the Arctic Ocean receive large amounts of this terrestrial OC from Eurasian Arctic rivers and from coastal erosion. READ MORE
